Audyssey powered components

I'm kicking around the idea of replacing my (ARC LS 25) preamp with a pre-pro so that I can use full range Audyssey room correction (gasp!). Two channels, with subs, audio only. Balanced out would be necessary and any advanced decoding/video capabilities would be welcome but not a particular priority.

I've thought about the stand alone Audyssey box, but prefer the convenience of a single component.

For such an application, anyone have suggestion for:

1) Best choice when cost is not relevant
2) Best choice for +/- $2500

Thanks in advance
